CNMG120404 AH6225 Turning Insert — Tungaloy

A CNMG120404 AH6225 indexable turning insert designed for external and internal turning, offering a balanced combination of a sharp, stable cutting edge and universal suitability for stainless steels

• ISO rhombic CNMG geometry, 80° cutting angle
• PVD-coated carbide grade AH6225 for stainless steel
• Double-sided chipbreaker for versatile turning
• Cylindrical hole with secure clamping, 4.76 mm thick

Consistent metal-removal with a PVD-coated carbide grade

The insert delivers steady material removal thanks to its PVD-coated carbide composition and the universal AH6225 grade, developed for stainless steel. The coating enhances wear resistance at elevated temperatures and reduces built-up edge, which means longer intervals between indexings and fewer unexpected tool changes. The 0.4 mm corner radius supports reliable edge strength, combining a sharp cutting edge with robustness for medium turning. This results in improved process stability and a predictable tool life in mixed-production environments.

Broad compatibility and secure clamping for workshop flexibility

Built to the ISO 120404 specification and presented in the CNMG rhombic form, the insert features an 80° main cutting angle and a cylindrical hole for positive locating in standard holders. Compatibility with a holder is determined by form, clearance angle, tolerance class, fastening, size and thickness; the standardised geometry simplifies insertion into existing tool systems. The double-sided design and secure clamping reduce inventory needs while allowing straightforward reversal when a new cutting edge is required, improving uptime on both lathes and machining centres.

Practical benefits for production and application advice

Choosing this indexable insert supports cost-efficient production by combining a stable cutting edge with a chip control system suited to a range of stainless steel alloys. The double-sided chipbreaker helps maintain consistent chip formation under varying conditions, reducing rework and operator intervention. For optimal results, match the chipbreaker and grade to the specific stainless alloy, machining parameters and toolholder rigidity; when in doubt, request tailored advice to select the correct holder and cutting data. Metav Werkzeuge’s technical consultants can assist with feed and speed recommendations and holder selection for a seamless integration into existing processes.

FAQ

What materials is this insert best suited for? The CNMG120404 AH6225 insert is specified for machining stainless steel, with the PVD-coated AH6225 grade providing wear resistance and a stable cutting edge for medium turning tasks.

Which insert geometry and clamping does it use? The insert uses a CNMG rhombic geometry with an 80° cutting angle and a cylindrical hole for secure clamping; holder compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness.

What is the corner radius and how does it affect performance? The corner radius is 0.4 mm, which balances a sharp cutting profile with edge strength, supporting stable cuts and extended edge life in many turning operations.

Can the insert be used for internal turning as well as external turning? Yes, the indexable design and double-sided chipbreaker make the insert suitable for both external and internal turning, provided a compatible holder is employed.

What coating and grade does the insert have, and what are the benefits? The insert is PVD-coated and manufactured in the AH6225 carbide grade; this combination improves thermal stability, reduces adhesion on the cutting edge and supports consistent chip formation during stainless steel machining.
